Crankshaft Position Sensor: Description and Operation
Crankshaft Position (CKP) Sensor 24X
The 24X reference signal is used to improve idle spark control at low engine speed. The PCM uses the 24X reference signal to calculate engine rpm
and crankshaft position at engine speeds up to approximately 1250 RPM. If the PCM receives no pulses on this circuit, DTC P0336 will set and the
PCM will use the 3X reference signal circuit for fuel and ignition control. For additional information refer to Hall Effect Sensor, Ignition / Description
and Operation.
For DTC diagnosis refer to System Diagnosis / Diagnostic Tables / Diagnostic Trouble Code Tables. See: Powertrain Management/Computers and
Control Systems/Testing and Inspection
